BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofMandevilla plant, botanically known as Mandevilla sanderi andhereinafter referred to by the name ‘Lannewyork’.

The new Mandevilla plant is a product of a planned breeding programconducted by the Inventor in Malause, France. The objective of thebreeding program is to create new freely branching Mandevilla plantswith numerous unique and attractive flowers.

The new Mandevilla plant originated from a cross-pollination conductedby the Inventor in Malause, France in July, 2016 of a proprietaryselection of Mandevilla sanderi identified as code number si08-0426-044, not patented, as the female, or seed, parent with aproprietary selection of Mandevilla sanderi identified as code number sis346-0, not patented, as the male, or pollen, parent. The new Mandevillaplant was discovered and selected by the Inventor as a single floweringplant from within the progeny of the stated cross-pollination in acontrolled greenhouse environment in Malause, France in June, 2017.

Asexual reproduction of the new Mandevilla plant by stem cuttings in acontrolled greenhouse environment in Malause, France since August, 2019has shown that the unique features of this new Mandevilla plant arestable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Lannewyork’. These characteristics incombination distinguish ‘Lannewyork’ as a new and distinct Mandevillaplant:

-   -   1. Compact, broadly upright and vining plant habit.    -   2. Moderately vigorous growth habit.    -   3. Freely branching habit.    -   4. Glossy dark green-colored leaves.    -   5. Early and freely flowering habit.    -   6. Large flowers with red-colored petals and greenish        yellow-colored throats.

Plants of the new Mandevilla can be compared to plants of the femaleparent selection. Plants of the new Mandevilla differ primarily fromplants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Mandevilla are more compact and have        shorter internodes than plants of the female parent selection.    -   2. Plants of the new Mandevilla are more freely flowering than        plants of the female parent selection.

Plants of the new Mandevilla can be compared to plants of the maleparent selection. Plants of the new Mandevilla differ primarily fromplants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Mandevilla are more compact than plants of        the male parent selection.    -   2. Flowers of plants of the new Mandevilla have red-colored        petals whereas flowers of plants of the male parent selection        have rose-colored petals.

Plants of the new Mandevilla can also be compared to plants ofMandevilla x amabilis X Mandevilla hybrida ‘Lankentucky’, disclosed inU.S. Plant Pat. No. 29,849. In side-by-side comparisons, plants of thenew Mandevilla differ primarily from plants ‘Lankentucky’ in thefollowing characteristics:

-   -   1. Plants of the new Mandevilla have larger and more rounded        leaves than plants of ‘Lankentucky’.    -   2. Flowers of plants of the new Mandevilla have red-colored        petals whereas flowers of plants of ‘Lankentucky’ have brighter        red-colored petals.
